Ultra-simple 10m CW transceiver


The Lesser Chirpy was one of my designs from 10 years ago. It is one of the simplest transceivers you can make. As with all my designs, I  would be very surprised if you could not make it better! It works by FSK so the frequency shifts when the key is pressed. The first version had too much chirp!
